Following urethrolysis overactive bladder symptoms may remain refractory in 50% or greater of patients, which has a negative impact on quality of life and the impression of improvement after surgery. Detrusor overactivity demonstrated preoperatively may be useful for predicting who may have persistent overactive bladder symptoms despite an effective urethrolysis procedure.
Cystocele patients with MUI are at significant risk for postoperative urge symptoms regardless of DO, and counseling regarding persistent urgency is imperative.
Refractory overactive bladder (OAB) after urethrolysis for iatrogenic bladder outlet obstruction (BOO) is a clinical dilemma without established guidelines for management. We sought to evaluate the efficacy of sacral neuromodulation (SNM) in the management of this complex patient population. Retrospective review identified eight patients who underwent SNM secondary to refractory OAB after urethrolysis or sling take-down. SNM was performed with the Interstim device (Medtronic, Minneapolis) using a two-stage implant technique. SNM outcomes were determined subjectively during follow-up. Validated questionnaires were completed to assess symptom bother, patient satisfaction, and quality of life. Statistical analyses were conducted using Stata version 9.0. Six patients had a favorable response to SNM during test stimulation and underwent implantation of the implantable pulse generator (IPG). With follow-up of 15.7 +/- 11.1 months (6-34), all patients significantly improved, with three patients being dry and three patients having one to two urgency incontinence episodes per week. Patient-reported outcomes indicated that patients perceived themselves as very much improved (3) or much improved (3) after SNM, while those failing test stimulation perceived no change. Quality of life and symptom bother were significantly better in SNM responders vs nonresponders. SNM appears to be an effective and viable treatment option in this complex patient population. Further work is needed to determine clinical factors predictive of outcome and durability of response.
Installation of the Nephros Dual Stage Ultrafilter (DSU) added to a conventional hemodialysis unit to achieve ultrapure dialysate was tested in a group of 23 stable outpatients on chronic hemodialysis. Comparing the 6-month period prior to the installation of the filters (as baseline) to the 6-month period after the installation of the filters, we found a significant 40% reduction in the darbepoetin dose needed to maintain a stable hemoglobin level (p < 0.001). In addition, surrogate inflammatory markers, WBC count and serum albumin level, showed small but statistically significant improvements (p = 0.008 and p = 0.042, respectively). In conclusion, the use of the Nephros DSU to further reduce endotoxin exposure in chronic hemodialysis patients can result in improved erythropoiesis-stimulating agent (ESA) responsiveness and a lower ESA dose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
